Inorder to use your Binatone Wireless Router with BSNL Dataone broadband connection, you need to downgrade the firmware.
My router is Binatone DT845W. I got this router with my Airtel broadband connection in Bangalore.
When i shifted to Kerala, i took a BSNL broadband connection.
Airtel broadband executive had upgraded the firmware to DT4W-A1.006
For using BSNL connection, i downgraded the firmware to DT4W-A1.002
After the installation of the firmware, do the following.
Tab: Interface Setup -> Internet
Select Virtual Circuit as PVC2
VPI = 0 and VCI = 35
Disable all other Virtual Circuits.
ATM QoS = UBR
PCR = 0
ISP = PPPoA/PPPoE
Servicename = leave it blank
Username = username which you got from BSNL
Password = password which you got from BSNL
Connection = Always On
Get IP Address = Dynamic
NAT = Enable
Defaut Route = Yes
TCP MTU = 1454 or 1492
Dynamic Route = RIP2-B
